javascript - React.js + axios : How do I avoid hard coding data on my datatable?

Question

我对 React 还很陌生，我正在使用这个名为 axios 的库来进行 API 调用。

我成功获取了我的网络应用程序的登录数据。但是，我很难将其应用到数据表上。

这是代码:

ClientMaintancePage.js

    import React, {useState, useCallback} from 'react';
    import { MDBCard, MDBCardBody, MDBBreadcrumb, MDBBreadcrumbItem, MDBDataTable, MDBCol, MDBBtn } from 'mdbreact';
    import 'react-bootstrap-table-next/dist/react-bootstrap-table2.min.css';
    import BootstrapTable from 'react-bootstrap-table-next';
    import paginationFactory from 'react-bootstrap-table2-paginator';
    import filterFactory, { textFilter } from 'react-bootstrap-table2-filter';
    import ClientMaintenanceService from '../../services/ClientMaintenanceService';
    import { ClientSaveSuccessModal } from '../modals/ClientSaveSuccessModal';
    import { ClientSaveFailedModal } from '../modals/ClientSaveFailedModal';

    const ClientMaintenancePage = () => {

      const [clientName, setClientName] = useState('');
      const [accountNumber, setAccountNumber] = useState('');

      const [disabled, setDisabled] = useState(true);

      const [showSuccessModal, setShowSuccessModal] = useState(false);
      const [showFailedModal, setShowFailedModal] = useState(false);

        const data = [

    export default ClientMaintenancePage;

看到那些硬编码的数据了吗？我想通过使用 API 调用使其动态化。

如果我所做的事情是正确的，请指导我。

ClientMaintenanceService.js

    import axios from 'axios'

    const API_URL = 'http://localhost:8080'
    const API_URL2 = "https://api.mockaroo.com/api/2883cf10?count=1000&key=262bee40"

    class ClientMaintenanceService {

        saveClientDetails(clientname, accountnumber) {
            console.log("ClientMaintenanceService post request>>> " + clientname + " " + accountnumber)
            return axios.post(`${API_URL}/saveclientmaintenance`, {
                clientname,
                accountnumber
            })
        }

        retrieveClientDetails(){
            return axios.get(`${API_URL2}`)
        }
    }

    export default new ClientMaintenanceService()

然后我会在我的页面中调用retrieveClientDetails()。

    const fetchRequest = useCallback(() => {
        ClientMaintenanceService.retrieveClientDetails()
        .then((response) => {

        }).catch(() => {

        })
      });

但是，我应该抛出什么参数？假设我想获取所有数据。

TIA

--编辑--

ClientMaintenancePage.js

    const [data, setData] = useState([]);

      useEffect(() => {
        retrieveAllClient();
      }, []);

      const retrieveAllClient = useCallback(() => {
        ClientMaintenanceService.retrieveClientDetails()
        .then((response) => {
          console.log("retrieveAllClient response.data>>>" + response.data)
          setData(response.data)
        }).catch(() => {
          console.log("retrieveAllClient catch>>>")
        })
      });

Answer 1

加载页面时，您需要useEffect来setData

import { useEffect, useState, useCallback } from 'react';

const [data, setData] = useState([]);

const fetchRequest = useCallback(() => {
    ClientMaintenanceService.retrieveClientDetails()
    .then((response) => {
         setData(response.data);
    }).catch(() => {})
});

useEffect(() => {
   fetchRequest();
}, []);
